  • Publication number: 20240380327
    Abstract: A power conversion system includes a high voltage (HV) switchgear; a solid-state transformer; and a low voltage (LV) switchgear. The HV switchgear connects to and disconnects from a HV or medium voltage (MV) network. The HV switchgear connects to an input of the solid-state transformer. The solid-state transformer comprises a first module and a second module. The first module converts a HV alternating current (AC) signal into a HV direct current (DC) signal. The second module connects to an output of the first module and converts the HV DC signal from the first module into at least one LV DC signal. The second module comprises at least one sub-module that converts the HV DC signal from the first module into a LV DC signal. The LV switchgear connects to an output of the solid-state transformer.

  • Patent number: 11141551
    Abstract: A ventilation drive (10) for an anesthesia device and a method for operating such a ventilation drive (10) are provided. The ventilation drive includes a blower unit (12), a pressure chamber (14) and a flexible bag (16) located in the pressure chamber (14). An internal volume of the bag (16) is coupled to an inspiratory branch (20) of a ventilation line. The blower unit (12) can be coupled to the internal volume of an outlet side and to an air inlet (26) for feeding ambient air on an inlet side. Further, a flow sensor (36) is provided between the outlet side of the blower unit (12) and the pressure chamber (14).

  • Publication number: 20140318540
    Abstract: A respiratory circuit gas removal device (1) has a inhalation branch subsection (2), a exhalation branch subsection (3) and a tube connection subsection (4), with a tube connection opening (5) for a tube adapter (17). The inhalation subsection connects to the tube subsection via a first opening (6), and the exhalation subsection opens into the tube subsection via a second opening (7). A gas removal tube (8) extends from the tube subsection to a removal opening (11), essentially concentric with a tube adapter opening (18). A tube end face (25) connects an edge (24) of a first end (12), which delimits an outer wall (8a) of the gas removal tube, to an inner wall (8b) of the gas removal tube surrounding the removal opening (11). At least 40 percent of the end face (25) is in a funnel shape and has an opening angle (15) between 130° and 170°.

  • Patent number: 8800553
    Abstract: A respirator or anesthesia apparatus for the artificial respiration of a patient is provided with a gas delivery device, at least one gas line for forming a breathing air line system, at least one device for measuring a volume flow of a gas according to the differential pressure method with a flow channel, a first pressure-measuring point and a second pressure-measuring point. The second pressure-measuring point is arranged in the direction of flow of the gas to be measured after the first pressure-measuring point at the flow channel. Furthermore, the flow channel is split into at least two separate partial flow channels in the direction of flow of the gas to be measured between the first pressure-measuring point and the second pressure-measuring point.
